[Text|High-tech LED Xu Chaopeng] Entering 2015, various new types of heat-dissipating materials and advanced optical designs in the LED industry circle emerge in an endless stream. In the face of the increasingly severe industry competition, we also hope to achieve cost optimization of LED lighting products in a certain way while ensuring product performance.
However, among the many innovative designs, a new technology is particularly prominent, which is the LED light engine technology that can further reduce the cost of LED light sources and lighting products.
It is understood that the development of LED light engine technology began around 2010. At first, people integrated LED light source lamp beads and driving power chip on an aluminum substrate or ceramic substrate to form LED light source board and LED power supply. A "photoelectric engine".
"LED light engine refers to the overall combination of LED package (component), LED array (module), LED driver and other brightness, thermal, mechanical and electrical components, first launched by nine international lighting companies such as Philips, Osram, Panasonic and Toshiba. And proposed by the Zhaga International Alliance, an LED industry cooperation organization established in 2010, to promote the standardization of lighting products and realize the interchangeability of LED light source products among manufacturers." Deputy Director of High-tech Research Institute LED Research Institute (GGII) Zhu Yuan pointed out.
"With the new LED light engine solution, transformers, inductors and electrolytic capacitors that require a lot of manual plug-ins can be eliminated in production. LED whole lamp companies can eliminate the need to consider the development of drive power and light source, which greatly saves the development process. The manpower, material resources and financial resources needed, and can get higher light efficiency.†Ma Feifeng, general manager of Effie Optoelectronics, told reporters.
It is understood that Effie Optoelectronics, founded by Professor Mao Yuhai who has been focusing on LED light engine research for several years, has developed a 60W light engine with a luminous efficiency of 140lm/W and an 80W light engine with 135lm/W. These light engine products are mainly used in the fields of street lamps, high pole lamps, high-power industrial and mining lamps and floodlights, floodlights and the like. According to Ma Shaofeng, these light effects are all lighting effects, including the efficiency of the power supply.
“What we have to do is to achieve the highest efficiency at the lowest cost and the smallest volume. The light efficiency of our products can reach 130lm/w or even higher than the whole lamp. Compared with the current light effect on the market is 100lm/ w similar products, we have improved the light efficiency of about 30% for customers, bringing about 30%-50% cost savings." Ma Shaofeng said that the price advantage of the light engine in this way is undoubted.
"This high-power light engine has a power factor of 0.95 and can be applied to street lamps, high-power industrial and mining lamps and floodlights. The total number of street lamps in China is about 30 million ç›, assuming that each street lamp is changed to LED. The power is 140W. After adopting Effie's light engine, it only needs 100W, and each shovel saves 40W, which can save 1.2 million kilowatts. According to the 5 hours of lighting every day, it can save 2.19 billion kWh of electricity every year.†Ma Shaofeng mentioned .
“As long as the light engine manufacturer guarantees extremely high performance and quality, migrant workers can also produce international-level LED lighting products.†Professor Mao Yuhai, Chairman of Effie Optoelectronics, vividly described the changes brought by the light engine. The optical and electrical specifications of all LED luminaires are developed by the light engine manufacturer. While ensuring the quality of LED luminaires, the LED luminaires can be greatly reduced.
"Since the development of light engine technology, many LED lighting application manufacturers have begun to focus on, and thus claim that application-based interchangeable LED light engine technology and integrated packaged light engine will become the focus of research and development. Initially expected in the future In two to three years, the LED light engine will reach a market share of more than 20%." Chen Heng, general manager of the green integration of the disc.
Therefore, based on such broad market prospects, foreign companies such as Seoul Semiconductor and Lynk Labs Inc. of the United Kingdom are vigorously promoting the application and production of optoelectronic integration. The US chip giant Texas Instruments has Extend their products to the LED optoelectronic engine drive field.
At the same time, in recent years, domestic LED fields such as Hongli Optoelectronics, Xinli Light Source, Meiya Optoelectronics, Changyuntong, Guangmai Electronics, Zhonghao Optoelectronics, and Liyang Optoelectronics have also begun to enter the LED light engine market.
"LED light engine is like the brain of lighting products. Its structural design, electrical index and optical performance index are more in line with the characteristics of LED products. I believe that the promotion and application of light engine technology will completely change the downstream lighting and technology and concept. Lighting industry." Jin Hongbing, director of the new light source light engine business unit mentioned.
